This system has been formulated to naturally block DHT (Dihydrotestosterone). DHT prevents nutrients from being absorbed by hair follicles, causing the shrinking of the follicles eventually, hair thinning, and hair loss. Natural ingredients such as Saw Palmetto, Pumpkin Seed Oil, Tea Tree Oil, Stinging Nettle, Soybean Oil, to name a few are commonly used to help block DHT. HEALTHY HAIR STARTS WITH A HEALTHY SCALP!
